    I have a 1999 honda civic. As of a couple of weeks ago when I turn on
    my heater/air cond
    it sounds like a loud lawnmower, Its so loud I cant even hear the
    radio. Any suggestions
    as to what this might be?

  2. If it started suddenly, I suspect a piece of debris has made its way into
    the fan. I don't know how access is in your Civic; maybe somebody else will
    know. It's also possible it can be removed by turning the fan low and
    setting the heater to "recirculate," then using a vacuum cleaner to suck the
    debris out the recirculation pickup (maybe the same person will know where
    that is).

    Thanks Mike, its not to accessible, the dash has to be removed. It
    sounds like the motor is going out

    No, it's probably not the motor, it's most likely leaves in the fan cage.
    I pulled the fan out of my Mums '99 Civic at the weekend and cleared out a
    ton of leaves all the way from the air inlet above the fan to the pollen
    filter. You can access some of Honda's workshop manuals from here and see
    how it all goes together, choose the Civic 1995-1997 it's got the same
    internals as your 1999 model:


    In a nutshell: you remove two screws at the hinge or the glovebox and put
    that to one side and then unclip the power connector to the fan (underneath
    the passengers right foot), unscrew 3 screws (8mm socket required DON'T use
    power tools or you'll strip the plastic!!) the fan can then be dropped out
    with a bit of wriggling to clear the trim panel in the footwell and cleaned
    out. Then remove 4 screws (again 3 require an 8mm socket 1 needs a 10mm
    socket) holding the metal bar at the base of the glovebox, drop one end to
    the floor and you can then remove the access panel to the pollen filter and
    clean out the duct from the fan to that point. Put it all back together and
    check you have no spare parts left over and it'll be quiet again. You may
    need to replace both the pollen filter and/or the resistor pack (it controls
    the fan speed) the resistor pack sits immediately above the fan and is held
    in place with two screws just pull it and visually check the 3 coils to see
    if they are burnt or brittle; change it if it looks bad.
